Specification of ;I.etters Patent.

s i i'eeeees l e, we see ler tes- Zlo all (whom it may concern Be itknown that I, JONATHA BRAss- FLELD, a citizen of the United States,residin at P eor ia, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Fumigating Devices; andI .do hereby declare that the following is a full, clear, and exactdescription of the invention, :which will enable others skilled in theart ,to which it ,appertains to make and use the same.

This invention relates to a fuinigatingapparatus particularly of a typethat includes a closed vessel in which to place the articles to befumigated together with the fumigah ing chemicals.

The object of ,the invention to provide an air-tight receptacle in whichto place a t l to b iilmi ete an Pa t u a y adapted for use in suchplaces hospitals, alrnshouses ,and the like.

To the nd tha the nvent n m y b thoroughly nderstoqd I have provided theaccompanying drawing in which:

dligure'l shows the device in ertical section; Rig. 2 is a plan of theupper portion of the ,b'odyqot' the device on a greatly reduced scale.Fig; ,3 isa plan ota diaphragm or plate located within the body and alsogreatly reduced insc ale.

C is aa lid having a dependingflange 1) adaptedto venter between the bodylof said sectlon A andtheflange B and whichmay rest upon the latteras shown.

Secured to the wall of the body Apreferalolyflnear the bottom is a ,box,or inclosure a the interior of which communicates with theinterior,ofthe saidbody A as shown. In the wall of thebox isan apertured coveredat fide by a a v b ee t e by va some i i i te sel th aerleeeete PatentedFeb. 24, 1 914.

near the top, for example, is a valve box A This may be carried by thesection A as shown or by the body A as may be desired. Said boxcommunicates with the interior of the apparatus and has an aperture 0closed within the box by a valve A carried by a spring A*.

The valves b A may be placed directly on the walls of the apparatus ifdesired, the boxes a A being used merely in order to provide a flatsurface for the valve instead of a curved surface such as would beprovided by the body of the apparatus if the latter is cylindrical inform. Ifthe body has a fiat surface, however, such as would be provided,for example, by making said body square in form, the boxes would not.berequireda channel formed by the flange plate E, after which the Inusing the device the receptacle H is first charged with the crystals orother forms of materials for producing the fumes, then the body A is setin position upon the garments, or other articles, are suspended in thebody. After placing the lid C in position, the joints are, sealed byplacing water in the upper B and the body A, in the lower channelbetween the flange F and the ring G and in the channel formed by theflanges 2 and 3. Now by removing the plug 0 any proper chemical toproduce reaction upon the material in the .receptacle H is poured intothe funnel N and this finds its way to the said receptacle H through thepipe M and the aperture K of the lid J. The fumes from the chemicals nowpass out through the hole K or apertures L of the receptacle H upthrough the apertures P of the diaphragm P into the ]Body to fumigatethe articles within the ody. V The device is of considerable value inhospitals, jails, workhouses, almshouses and like institutions wheregarments or bedding infested with vermin or with disease germs are to berenderedclean and serviceable, and bv constructing the device of largesize considerable quantities of bedding clothing and the like can betreated, as is evident. The device is also well adapted for special useas, for example, in the fumigation of p the garments of nurses, doctors,and their assistants in hospitals and the like.

It. is observed that water, oil, or other liquid, that may be employedfor sealing purposes will absolutely prevent the escape of fumes causingno annoyance therefore to persons working about the device. As anadditional safeguard against leakage of fumeswater or other liquid canbe poured into the funnel N to seal any slight opening that may existaround the plug 0. The dia- V phragm or plate P, as before stated, has acentral imperforate portion directly above the receptacle H so that incase fluid is thrown upward by chemical reaction it will not be thrownupon the clothing being fumigated.

The receptacle existing within the ring G on the bottom E may, ofcourse, be used for the chemicals in place of the receptacle H, ifdesired, although by using the latter the device may be more readilycleaned.

The apparatus is capable of ready enlargement by adding as many of thesections A as desired so that articles of great size or length can beaccommodated.

The gas formed by the chemicals will increase the pressure in theapparatus slightly above atmospheric pressure and in order to enable theair to escape under this increase I provide the valve 6 through whichthe air can readily escape. Again, in case a partial vacuum forms in theapparatus due to condensation or other causes the valve A serves toadmit the outer air to equalize the pressure.

Having thus described my invention, 1 claim:

1. In a fumigating apparatus the combination of an air tight receptaclefor the article to be fumigated, a vessel to receive a dis infectingmaterial having a perforate wall, a funnel shaped cover-plate for thesame having a. single opening, and a conduit extending into thereceptacle and terminating at one end above said cover-plate andterminating at its other end outside the receptacle.
